Cohen effect size after fixelcfestats

Hi Mrtrix3 Users,

Questions and replies may been posted earlier. I just need to be clarified for reporting effect size after fixelcfestats, which I had the “Global intercept & group difference” design

Design:
1 1 #
1 1 #
1 1 #
1 1 #
1 -1 #
1 -1 #

Contrast:
0 1 0
0 -1 0,
where the “1” in the second column of design is control, and “-1” is patient.
If I need to the patient effect, the Cohen d would be the std_effect_t2.mif, correct?

Do I need to make any adjustment to LogFC?

Thank you.
